Constructor Detail

PKCS8EncryptedPrivateKeyInfo

public PKCS8EncryptedPrivateKeyInfo(org.bouncycastle.asn1.pkcs.EncryptedPrivateKeyInfo encryptedPrivateKeyInfo)

Wrap an existing parsed EncryptedPrivateKeyInfo structure.

Parameters:

encryptedPrivateKeyInfo - the ASN.1 structure to wrap.

PKCS8EncryptedPrivateKeyInfo

public PKCS8EncryptedPrivateKeyInfo(byte[] encryptedPrivateKeyInfo)
                             throws java.io.IOException

Parse a BER/DER encoded EncryptedPrivateKeyInfo.

Parameters:

encryptedPrivateKeyInfo - the encoded bytes.

Throws:

java.io.IOException - if the data is not a valid EncryptedPrivateKeyInfo encoding.

Method Detail

getEncryptionAlgorithm

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getEncryptionAlgorithm()

Return the algorithm identifier describing how the private key has been encrypted.

getEncryptedData

public byte[] getEncryptedData()

Return the raw ciphertext bytes of the encrypted private key.

toASN1Structure

public org.bouncycastle.asn1.pkcs.EncryptedPrivateKeyInfo toASN1Structure()

Return the underlying ASN.1 structure for this holder.

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

Return the default (DER) encoding of this EncryptedPrivateKeyInfo.

Returns:

the encoded bytes.

Throws:

java.io.IOException - if encoding fails.

decryptPrivateKeyInfo

public org.bouncycastle.asn1.pkcs.PrivateKeyInfo decryptPrivateKeyInfo(InputDecryptorProvider inputDecryptorProvider)
                                                                throws PKCSException

Decrypt the wrapped private key.

Parameters:

inputDecryptorProvider - provider able to produce a decryptor matching the encryption algorithm carried by this object.

Returns:

the recovered PrivateKeyInfo.

Throws:

PKCSException - if a decryptor cannot be created or decryption / parsing fails.
